Filip

Mirko has a younger brother, Filip, who just started going
to school and is having trouble with numbers. To help him get
the hang for number scale, his teacher writes two three-digit
numbers. She asks Filip to compare those numbers, but instead
of interpreting them with the leftmost most significant digit,
he needs to interpret them the other way around, with the most
significant digit being the rightmost one. He than has to tell
the teacher the larger of the two numbers.

Write a program that will check Filip’s answers.

Input

The first and only line of input contains two three-digit
numbers, $A$ and
$B$. $A$ and $B$ will not be equal and will not
contain any zeroes.

Output

The first and only line of output should contain the larger
of the numbers in the input, compared as described in the task.
The number should be written reversed, to display to Filip how
he should read it.
